November 2022 in “Journal of Investigative Dermatology” This study found that innate lymphoid cells-type 1 can induce alopecia areata characteristics in human hair follicles both ex vivo and in vivo, challenging the view of it as solely an autoimmune disease driven by CD8+ T cells.
November 2022 in “Journal of Investigative Dermatology” This study provides evidence that ILC1-like cells can induce alopecia areata in previously healthy human hair follicles, challenging the view that it is solely an autoantigen-dependent autoimmune disease.
This study found that ILC1-like cells can induce alopecia areata symptoms in both ex vivo human hair follicles and in vivo mouse models, challenging the view that alopecia areata is solely CD8+ T cell-driven.
September 2022 in “Journal of The American Academy of Dermatology” This review summarizes existing literature on COVID-19-associated alopecia, finding that androgenic alopecia may increase COVID-19 risk, while telogen effluvium often follows infection.
March 2022 in “Wound practice & research” This review synthesizes current evidence on alopecia areata, detailing its clinical features, pathogenesis, and treatment options, but does not present new clinical results.
October 2021 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that the proprietary aptamer TAGX-0003 significantly inhibited IFNγ-induced effects in pre-clinical human models of alopecia areata, promoting hair regrowth and potentially preventing disease relapse.
August 2021 in “Journal of Investigative Dermatology” This study found that ILC1-like cells can induce alopecia areata in healthy human hair follicles, suggesting that these cells might be a therapeutic target in AA management.
April 2021 in “Sohag Medical Journal” This review outlines the proposed theories behind the development of alopecia areata, emphasizing the autoimmune process involving lost immune privilege in hair follicles, and stresses the need to pinpoint specific pathogenic mechanisms for potential treatments.
July 2020 in “DOAJ (DOAJ: Directory of Open Access Journals)” This review suggests that excessive facial photoprotection could play a role in frontal fibrosing alopecia through a disturbance in immunological balance via the aryl hydrocarbon receptor-kynurenine pathway.
September 2019 in “Journal of Investigative Dermatology” This study suggests that in alopecia areata, innate lymphoid cells type 1 may contribute to the disease’s pathogenesis by inducing hair follicle changes similarly to CD8+ T cells.
September 2019 in “Journal of Investigative Dermatology” This study found that epidermal growth factor receptor and mitogen activated protein kinase inhibitors down-regulate PD-L1 expression in human hair follicles, which may contribute to sterile folliculitis in treated patients.
April 2018 in “The journal of investigative dermatology/Journal of investigative dermatology” This study suggests that miR-486 may protect against alopecia areata by maintaining hair follicle immune privilege and modulating expression of immune-related genes.
April 2018 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that electrical epilation in organ-cultured human scalp skin perturbs hair follicles by causing inflammation, impairing melanin production, and possibly inhibiting post-epilation hair re-growth.
April 2017 in “Journal of Investigative Dermatology” This study found that miR-486 and miR-451 levels were reduced in alopecia areata-affected skin, and delivering their mimics to mice mitigated symptoms by reducing inflammation and immune activity.
This review discusses the pathogenesis and new treatments for alopecia areata, highlighting the role of the hair follicle's immune and hormone systems and potential therapies like JAK inhibitors and immunomodulators.
